Short term threshold instabilities may cause analog circuits like comparators and analog-to-dig conventional characterization procedures have not sensitized to such issues, this kind of erratic beh occurs in products where it is very difficult to iden example prior to the introduction of a new gate sta do a careful experimental characterization of sh instabilities, which goes beyond standard me...

This work aims the precise control of the piezoelectric actuators that can theoretically provide unlimited motion resolution. For this purpose Sliding Mode Controller (SMC) is used. The proposed algorithm is known to have order of sampling time square and therefore faster application than DSP was required. The application of the algorithm via analog electronics is suggested. Preliminary work, s...

Analysis of analog filter of fractional order is the main objective of this paper. The basics of fractance device are studied. Rational approximation of fractional order operator using continued fraction expansion is carried out. Analytical expressions of the differentiator operator for different input signals have been developed and simulated in MATLAB software and corresponding simulation res...

| This paper presents an event-driven algorithm for the symbolic analysis of power and ground bus networks using moment matching techniques to estimate the transfer function at each node in the P/G network. The P/G network is modeled by a hierarchical combination of mesh and tree structures that are composed of a collection of RCsegments and pulldown (or pullup) switches. The switches are symbo...

optimization technique for fault diagnosis of nonlinear analog circuits with tolerance. This paper deals with fault isolation in nonlinear analog circuits with tolerance under an insufficient number of independent voltage approach is proposed and utilized in locating the most likely faulty elements in nonlinear circuits. The validity of the proposed method is verified by both extensive computer...

A digital to analogue converter (DAC) based on a single-electron tunnelling transistor (SETT) is proposed. The proposed scheme fully utilises the Coulomb blockade effect and only a SETT and n+1 capacitors are necessary for an n-bit DAC implementation. Using this scheme, a 4-bit DAC is demonstrated by means of simulation.

It is shown that a digital simulation of a noise induced phase transition using an algorithm consistent with the Ito stochastic calculus is in agreement with the predictions of that theory, whereas experiments with an analogue simulator yield measured results in agreement with the predictions of the Stratonovich theory.

this paper presents a comparative analysis between two current control strategies, constant source power and generalized fryze current, used in active power filter (apf) applications having three different modulation methods. the hysteresis band (hb) and first-order delta-sigma modulation (dsm) as well as the second-order dsm is applied. the power section of the active power filter is viewed as...
